Abstract
This paper describes a new modulation scheme for digital radio communication. A 3rd order cosine pulse waveform is introduced to the Bennett´s raised cosine pulse. By using this pulse, a flat region is generated with respect to a decision point. It is thus possible to improve the immunity to the effects of digital signal jitter. The spectrum of this pulse was calculated, and compared to the Bennett´s raised cosine pulse.
